The collection features three products: Hinoki Body Milk, Hinoki Body Wash, and Hinoki Body Oil. You're probably wondering, what is Hinoki? Well, for this collection Tatcha worked very close with Qing Li, MD an expert in forest medicine, who spoke to explain how forest bathing ties in with Hinoki. "The Japanese Hinoki is one of the trees that I've studied the most since Hinoki forests were the birthplace of forest bathing in Japan," says Dr. Li. He adds that Hinoki is an evergreen tree, meaning it stays green for many seasons, producing high levels of essential oils throughout the year. "I've studied multiple types of trees' essential oils, and Hinoki has proven to be the most beneficial of forest oils in terms of mental and physical benefits."
